Hi folks,

this is a request from a colleague who runs my mail server...has
anyone ever seen this sort of behavior?  We're sort of baffled...

Cheers,

-John

The net which this (zog.net, 88.net) host runs on is currently somewhat
disabled by a few Windows XP boxes which insist on broadcasting bogus UDP
multicast packets out through the DSL link.  I wondered if any of you had
encountered similar problems in the past, and if any of you might have a
solution.  The host lives on my brothers' DSL in New York; he doesn't seem
able/willing to diagnose and solve the problem, which unfortunately also
brings down the router periodically.

Basically, various hosts are broadcasting packets destined towards
224.0.1.24 (MICROSOFT-DS is the name of this destination) on port 42.  The
volume of traffic is typically sufficient to fill the link; although
sometimes (bafflingly) only exactly 50% of available bandwidth appears to
be consumed (examining MRTG graphs).  The traffic consists of many small
packets -- 500-800 per second, which appear to be roughly all the same in
content.  One of the hosts is the other side of a linksys wireless AP; not
sure if this is relevant or not.

Anyway -- if anyone has seen this before, I'd be interested to know what
you found.

cheers,

Thomas
